c ouPLING DEVICE.

SPECIFICATION forming part of Letters Patent No. 663,009, dated December4, 1900.

Application led February 6, 1900. Serial No. 4,187. (No model.)

To a/ZZ whom t may concern:

Be it known that I, WARREN B. CANNON, a citizen of the United States,residing at the city of Kalamazoo, in the county of Kalama- Zoo andState of Michigan, have invented certain new and useful Improvements inCoupling Devices, of which the following is a specification.

This invention relates to improvements in couplings for hoops or bandsfor tanks, tanksilos, tubs, or for bands for any similar purpose.

The objects of the invention are, first,to provide a simple andefficient means of joining the ends of hoops or bands together Withoutthe necessity of riveting the same; second, to provide a means of sojoining the ends that they may be easily detached; third, to providesuch a coupling means which can be conveniently and effectively used inconnection with a tightening-bolt, and, fourth, to provide a simple andeflcient coupling for the ends of a hoop or band which will notinterfere with the driving of the hoop on a tank or barrel to draw thestaves closely together.

A still further object is to simplify the construction and provide acoupling which does not injure the tensile strength of the band or hoop,but preserves it to the fullest extent without the use of rivets,Welding, orsimilar means and which may be readily and convenientlyapplied without the use of special appliances.

Further objects will definitely appear in the detailed description tofollow.

I accomplish these objects of my invention by the devices and meansdescribed in this specification.

The invention is clearly defined and pointed out in the claims.

A structure embodying my invention is clearly illustrated in theaccompanying drawings, forming a part of this specification, in WhiohyFigure l is a detail elevation view of my improved coupling device inposition, the same being adapted for use with a tightening-bolt. Fig. 2is a detail longitudinal horizontal sectional elevation of the same,taken ou line 2 2 of Fig. 1. Fig. 3 is adetail inside elevation view ofone end of the coupling device. Fig. 4 is a transverse detail sectionalview of one lug or member, taken on line 4 4 of Fig. 3. Fig. 5 is adetail view of a modiiication of the device in which no tighteningboltis used. Fig. 6 is a longitudinal horizontal sectional view taken online 6 6 of Fig. 5.

In the drawings all of the sectional views are taken looking in thedirection of the little arrows at the ends of the section-lines, andsimilar letters of reference refer to similar parts throughout theseveral views.

Referring to the lettered parts of the drawings, A represents a tank,tub, or other similar receptacle composed of staves in the usual manner.

i B B represent the ends of the hoop or band embracing the same.

' C C represent the end brackets or lugs of my improved coupling, whichare joined together by a bolt D, having a screw-threaded nut fortightening the same. The lug C has side or cheek pieces connected by anouter and inner web, the outer containing suitable perforations for thetension-bolt D, to which I have referred. Where the sides of the lugcome in contact with the tank or tub they are curved slightly and haveoutwardly-extending projections r to make it possible to drive the samewithout their gouging into the staves. Within the side or cheek piecesof the lug are inclined Ways E. On the inner web joining the sides is alittle transverse ridge n.

In use the end of the band or hoop is folded inward uponitself around apin E, which is of sufficient length to rest between the side or cheekpieces of the lug and engage the inclined Ways E. The end of the bandorhoop B is folded to the-inside and inserted through the centralaperture of the lug and the pin E inserted through the loop when thehoop is drawn/back into place. As tension is put on the band bytightening the bolt D or driving the hoop it draws the same so that theridge n clamps the free end of the bandsecurely against the outerportion of the band, and as the strain is increased it carries the pin Ealong the inclined portion E', clamping the parts more securely.

It will be observed that the texture of the IOO band is uninjured by anysharp bends, it embracing over the pin E in a fold, which pin Where thecoupling-bolt is used, the lugs are very easily put upon the band orhoopafter it is in position. The bolt is then inserted and the sametightened up,when the band can be driven tight and by so doing greatlyincrease its tension. However, the invention is adapted for useindependent of any tightening-bolt, as appears in the structureappearing in Fig. 6, where the outer web portion of each lug is joinedtogether, and in that event the hoop or band is coupled before it is putover the staves, when it can be driven down tight into position, owingto the special structure which I have mentioned in this connection, thesame being usedas though the ends of the hoop were joined together byrivets in the usual way.

I desire to state that Ihave shown my irnproved coupling device or lugsin what practical use demonstrates thus far to be the best form, thoughmy experience 'indicates that the same can be made in other forms and bequite effective. The coupling device will be quite effective if it isnot made with the inclines E', although they are valuable and in sureits effective action, and the exact method of joining the lugs togetheris not an absolute essential, as appears in thel description referredto. It might where broad bands are coupled together be desirable toprovide the same without other means than the single bolt D, which Ihave here described.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a coupling device for hoops or bands,

-the combination of a pairof lugs C having sides or cheeks joinedtogether by an outer and inner web; inclined ways E' on said cheeks;
